ADJUSTABLE PRESS.

SPECIFICATION forming part of Letters Patent No. 631,573, dated August22, 1899.

Application filed August 8, 1898, Serial No. 688,100- (No model.)

T0 at whom it may concern:

Be it known that we, WILLIAM C. KELLY and JAMES P. KELLY, citizens ofthe United States, residing at Alexandria, in the county of Madison andState of Indiana, have invented certain new and useful Improvements inAdjustable Presses, of which the following is a specification.

In the manufacture of axes, hatchets, and such like tools that varietyof dies known as box-dies are most generally employed in giving theforgings their proper form. Such dies are commonly composed of twomating halves, each containing one-half of the matrix-cavity. It is, asis well known to axmanufacturers, desirable to make each size or varietyof axes (while otherwise the same) of several different sizes orweights, the difference in weight being in the head or poll of the axabove the eye for the handle. For example, when axes of three differentweights of any given size or variety are required (as four pounds, fourand one-fourth pounds, and four and one-half pounds) it becomesnecessary to make three complete sets of dies, with the attendantmultiplication of expense. The cutting of matrix-cavities in die-blocksis at best a work involving considerable labor, especially in the makingof box-dies, in which the head or poll end of the cavity must be chippedand filed out by hand. Thework of making open dies is much more easilyand less expensively performed and may be mostly done on a planing ormilling machine. These open diesthat is, dies with the head ends cut orplaned completely out, thus permitting the heated metal of the blankbeing operated upon to flow out from the eye toward the head end of theax or other forging have in themselves long been well known; but themeans of confining the metal therein has been unsatisfactory, or when nomeans for confining it were provided and the work of. finishing theax-poll was left to a subsequent operation the labor, and consequentlythe expense, has been greatly increased. Of the means for confining themetal some have had a yielding character, with the result thatcontinuallyvarying and uncertain sizes and qualities of axes wereproduced, and some have had complicated and difficultly-operatedmechanisms.

The object of our present invention is to provide'a press in which allthe advantages 'of solid box-dies may be secured, while the dies can bevaried definitely to permit the manufacture therein of two or morecertain, definite,and predetermined sizes of axes,thus reducing thenumber of dies necessary to be used, and enabling said dies themselvesto be produced at about the cost of ordinary open dies.

A machine embodying said invention will be first fully described,and thenovel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts, Figure 1is a side elevation of a droppress, otherwise of an ordinary andwellknown form, embodying our present invention; Fig. 2, a horizontalsectional view, on an enlarged scale, showing the parts to which saidinvention especially relates in top plan, as seen from the dotted line 22 in Fig. 1; Fig. 3, a vertical sectional View on the dotted line '3 3mFig.2; and Fig. 4,a horizontal sectional View, on a still furtherenlarged scale,

on the dotted line 4 4 in Fig. 3, showing the details of construction ofour preferred means of adjusting the head-die more plainly.

As hereinbefore indicated, this invention is intended to be applied toand used with the ordinary drop-press commonly employed in themanufacture of axes and such like arti- 'cles. In the drawings theportions marked A represent the columns or frame of such a press, 13 theanvil, and O the drop. The die members D and D are the ordinary box-dieswith open ends. Within these open ends a third or head die E is placed,and this die is carried upon the end of a heavy rigid bar F, whichextends to outside the'frame of the press, where a heavy rigid fixedabutment is provided. This abutment preferably consists of two heavyuprights G, having a space between them siiflicientlylarge to permit theinsertion and withdrawal of the bar F and a heavy metal plate H, securedto the face of said uprights. This plate has a central opening throughwhich the bar may pass and a mortise arranged transversely to saidopening, within which a block I may be placed. This block is adjustable,so that any desired position of the bar F may be provided for. As bestshown in Fig. 4, we have made the rear side of the mortisein the plateII, through which the block I passes, inclined and the correspondingsurface of said block tapered, so that said block as a whole is somewhatwedge-shaped, while its front side, against which the bar F bears, isnevertheless at right angles with said bar, so as to support it in themost direct and positive manner. Setscrews 3 or other suitable clampingdevices may be employed to hold the block firmly in its adjustedposition.

.Ve have shown a hanger-rod R, having a turnbuckle T therein foradjusting the posi tion of the bar F accurately; but manifestly anyother suitable supporting means may be employed, or a recess may beformed in the face of the block I, into the rear end of which said bar Fmay enter and by which it may be supported without the interposition ofany independent support. e prefer the rod R and turnbuckle T, however,as not only admitting of a ready assembling and disassembling of theparts, but as constituting an easy means of exact adjustment. It is alsoobvious that other means than that shown for adjusting the block I maybeemployed without departing from our invention, the adjustability of thisblock rather than the means of effecting the adjustment being theimportant feature of this element of the invention.

The die E and bar F are shown as constructed separately and separablyconnected. This is the most convenientconstruction and admits of theremoval of the die separately for change or repair; hutin use the twoparts are in effect integral and may be made so in fact withoutdeparting from our invention. Vhile the adjustment of the die E is shownas effected by the adjustment of the bar F and the point at which theadjustment of said bar F is madeis shown as at the extreme outer endthereof, of course the adjustment maybe made at any point desired, solong as the desired position of said die E is secured, without departingfrom our invention, although we regard the arrangement shown as probablythe simplest and best for the purpose.

It will be readily seen, as has already been indicated, that by the useof our invention we are enabled to use a single set of dies for severaldifferent sizes or weights of axes by merely adjusting the die Elongitudinally, while much of the tedious work of chipping and filing inthe manufacture of the dies themselves, which is inseparably incident tothe making of complete box-dies, is avoided, as well as the largeaccumulation of such dies where numerous weights of 'each pattern are tobe provided for. The greater portion of the labor incident to changingdies in the press, when a different weight of forging is desired, isalso completely dispensed with. The operation of the press in use issubstantially the same as when the ordinary solid box-die is used, andsecures an equal certainty and uniformity in the size and character ofthe product.

Having thus fully described our said invention, what we claim as new,and desire to secure by Letters Patent, is

1. The combination, in a press, of box-dies the cavities wherein areopen at one end, a third die entering and resting within theprolongation of the die-cavity, a stiff bar carrying said third die, arigid abutment for holding said bar,and means for adjusting thebearingface of said rigid abutment out or in,whereby the size of thedie-cavity may be varied and different and predetermined sizes offorgings thus produced, substantially as set forth.

2. The combination, in a press, of the upper and lower dies containingthe matrix-cavity, which cavity is prolonged on one side to the surfaceof said dies, a third die entering said prolongation, a rigid barcarrying said third die, a rigid supporting-abutment alongside said die,an adjustable block carried by said abutment against which said barcomes in immediate contact, and means of adjusting said block.

3. The combination, in a press, of box-dies the cavity wherein isprolonged to one side thereof, a third die resting in the prolongationof the die-cavity,a bar carrying said third die, a rigid abutmentagainst which said bar rests and by which it is held to itspredetermined position, means for adjusting said rigid abutment out andin, and an adjustable hanger supporting the outer end of said bar, whichrests against said abutment, substantially as set forth.

4:. The combination, in a press, of the upper and lower box-dies thecavity wherein is extended to one side thereof,.a third die resting insaid cavity, a bar carrying said third die, and arigid but adjustablesupport forsaid bar consisting of the uprights G, the metal plate orblock II secured thereto, and the movable wedge-shaped block I carriedin a suitable bearing therein, substantially as set forth.

5. The combination, in a press, of box-dies the cavity wherein isextended to one side thereof, a third die resting in the prolongation ofsaid cavity, a bar carrying said third die, an abutment for said barconsisting of two heavy uprights G having a space between them throughwhich the bar may be introduced to position, a heavy bridge-plate IIsecured to said uprights and having a central opening therein throughwhich said bar may pass and also provided with extensions containing abearing the rear side whereof is inclined, a tapered block I restingwithin said bearing, and means whereby the same may be secured inadjusted position, substaut ially as set forth.

In witness whereof we have hereunto set our hands and seals, atAlexandria, Indiana, this 3d day of August, A. D. 1898.
